Odd starting issue

[asshanson]

When I was looking at the CAS, it didn't seem like you could put it in upside down or anything, no moving parts, maybe magnetic? I'd check to make sure all your other sensors are still installed. I thought we tightened the CAS, but maybe not, maybe we left a few others hanging there to be put on later.

If those are all fine, check compression, fuel, and spark. Battery shouldn't be dead if it cranks fine.
